A solution we built for a client.
Alfresco DM: Users / authors login and create content, through a custom UI. Includes workflow, multi lingual content, versioning, editions etc.
Alfresco WCM: Authors use a publish button on the custom UI, which automatically copies the content and related assets to Alfresco WCM, transforms it to correct XML format and uses WCM deployment to deploy the content to remote Drupal instance.
Drupal: XML-RPC extensions to store the content in the Drupal database and work independently of Alfresco.
This de-coupled solution means Drupal can scale on it's own. Alfresco WCM enables publishing to one or more drupal instances. Easy to set up new Drupal instance and get it updated to the latest content.
